I don't have goats, or (so far!) bears, but without electric fencing there wouldn't be a fence still standing here. Horses eat treated lumber like candy, and both horses and cattle would rub it down in no time!
When we used wood, we found a local sawmill that sold green true 2"x6" oak boards, less expensive than treated, that the horses wouldn't eat. After ten or fifteen years, they ate them too, but electric fencing protects things very well. Only electric fencing works against bears!

Most of our pasture fencing for horses will be e- tape. Cheap, easy effective.
